Absiraci-Fixed step size random search for minimization of functions of several parameters is described and compared with the k e d step size gradient method for a particular surface. A theoretical technique, using the optimum step size at each step, is analyzed. A practical adaptive step size random search algorithm is then proposed, and experimental experience is reported that shows the superiority of random search over other methods for sufllciently high dimension.T

This paper presents a combinatorial analysis of a mathematical model of the Main Distributing Frame (MDF). Results are found concerning the amount of additional spare needed to convert a randomly connected MDF to a preferentially assigned mode of operation. The analysis is first performed for an MDF having two sections and serving one class of service. The results are subsequently extended to an MDF with multiple sections and several classes of service.
